ENGINE ASSEMBLY
 Always use the support point specified for lifting.
 Use either 2-pole lift type or separate type lift as best you can. If board-on type is used for unavoid-
able reasons, support at the rear axle jacking point with a transmission jack or similar tool before
starting work, in preparation for the backward shift of center of gravity.
 For supporting points for lifting and jacking point at rear axle, refer to GI-48, "

 If measured value is out of the standard, replace flywheel.
Movement Amount in Radial (Rotation) Direction
Check the movement amount of radial (rotation) direction with the following procedure:
1. Install clutch cover bolt (1) to clutch cover mating hole, and
place a torque wrench (A) on the extended line of the flywheel
(2) center line.
 Tighten bolt at a force of 9.8 N·m (1.0 kg-m, 87 in-lb) to keep it
from loosening.
2. Put a mating mark on circumferences of the two flywheel
masses without applying any load (Measurement standard
points).
3. Apply a force of 9.8 N·m (1.0 kg-m, 87 in-lb) in each direction,
and mark the movement amount on the mass on the transaxle
side.
4. Measure the dimensions of movement amounts “A” and “B” on
circumference of the flywheel on the transaxle side.
 If measured value is out of the standard, replace flywheel.Limit: 33.2 mm (1.307 in) or less.

Inspection and AdjustmentINFOID:0000000001381465
INSPECTION
1. Place the valves of the cylinder concerned at the “end of
exhaust - beginning of intake” position and inspect the clearance
(X).
NOTE:
Dimension (Y) corresponds to the tappet thickness sizes (there
are 25 sizes available).
2. Compare the values recorded with the values specified, then
replace the tappets which are not within tolerance.
ADJUSTMENT
1. The camshaft must be removed to replace the tappets after
determining dimension (Y).
2. Set up the following assembly using dial gauge stand
[KV113B0050 (Mot. 252-01) (commercial service tool) or equiva-
lent tool] and dial gauge, then calibrate the gauge.
3. Raise the gauge extension (without modifying the position of the
magnetic support/gauge assembly), then slide in the tappet to
be measured.
Note dimension (Y) and repeat the operation for the tappets
where the valve clearance is not within tolerance.
Select the various thicknesses of the tappet(s). 25 sizes of sin-
gle-piece tappets are available. Refer to EM-333, "
Camshaft". Clearance when the
engine is cold: Refer to EM-333, "
Cam-
shaft".MBIB0333E
